A new method for fabricating orbital prosthesis with a CAD/CAM negative mold

The challenge of fabricating an orbital prosthesis is how to position the iris and pupil properly. Computer simulation can be a more effective and simpler approach to measuring and evaluating these features than the conventional method. However, transferring the optimal position of the iris determined in the virtual design procedure to the real definitive prosthesis can be difficult. The purpose of this article is to demonstrate a method of fabricating an orbital prosthesis with a negative mold designed and produced by a computer-aided design and computer-aided manufacturing technique. With this method, the iris can be designed in the most favorable position, and this position can be transferred to the silicone prosthesis correctly.
